[Android]
Today it's Runtastic. I've already bought it from a sale a while ago but for those who haven't. Don't really use it but it was pretty cool when I did.
Download app
Go to app settings
Go to tab 'Enter Promotion Code'
Enter 'APPOFTHEDAY'
Don't remember if it was $4.99 or $5.49. Well the App of the Day app tells me it was $5.49 but I remembered $4.99.
FAQ:
Q. Yada yada something about a 10 days trial yada yada?
A. It's got to do with a special membership on the website that allows you to use 15 extra features that you don't really need. You should just ignore it, imo. If you're interested, click here to read more about it.
Q. Will I be able to keep the upgraded version if I uninstall and then reinstall the app?
A. I'd assume no. However I'd also assume that if you backed it up using Titanium Backup, you'd be able to keep it.
Q. My app doesn't say it's Pro!?
A. It'll only unlock the features of the Pro version onto your regular version (it'll still be the regular version, just with the Pro features). After you activate, you may need to restart the app to see changes.
Q. The code is not working or I'm getting an error when activating?
A. It needs to make a connection to the servers when you activate the coupon, so you need to enable data (Wi-Fi/3G).
So we need to download the Free version of Runtastic and enter the APPOFTHEDAY somewhere in the app? I'm having trouble understanding.
